Answer:

13.75%

Explanation:

Givens:

  • APR first days: 0%.
  • APR afterwards: 14.04%.

We have to find the effective interest rate, which is defined as:


R=(1+(r)/(365) )^(D)-1\\

First days:


R=(1+(0)/(365) )^(60)-1=1^(60)-1=0

Afterwards:


R=(1+(0.1404)/(365) )^(335)-1=0.1375 \ (or \ 13.75\%)

So, the effective interest would be the difference between these two, which is 13.75%.
